Electrochemistry has undergone a transition since the discovery of electrochemical polymerization of conducting polymers on the electrode surface. These films can be modified in order to give electrodes unique capabilities. This thesis presents an intensive study of novel conducting polymers based on the use of polypyrrole and poly(N-methylpyrrole), and new counter ions, single-stranded and double-stranded DNA. This research has established the polymerization kinetics which now allows the films on the electrode surface to be modified in order to perform specific tasks. The alternating current impedance of the films has been determined to understand their equivalent circuit parameters. EQCM presents a more thorough understanding of ion movement into and out of the film. A new biosensor composed of poly(N-methylpyrrole), ssDNA, and GOx is presented. This glucose oxidase sensor has short response times and holds promise of being able to determine glucose concentration in a human blood sample without addition preparation.
